"In 1982 the British nuclear submarine HMS Conqueror proved the conventional operational potency of the nuclear attack submarine by sinking the Argentine heavy cruiser General Belgrano during the Falklands, or Malvinas, War."

LOL. There wasn't much "proof" needed of that concept..... the General Belgrano operating anywhere within the operational area of the HMS Conqueror was on a suicide mission. The only question was whether the Brits would decide to sink her because they were showing a lot of restraint, IIRC. They could have sunk a lot more Argentinian ships if they'd wanted to.

The Argentinians forced their hand on that one. When the South American fleet split up, the Brits had to make a decision.

FYI, I just checked and found the following information about the "heavy cruiser General Belgrano":

USS Phoenix (CL-46), a Brooklyn-class light cruiser, was the 3rd Phoenix of the United States Navy. After World War II the ship was transferred to Argentina in 1951 and became known as the General Belgrano. General Belgrano was sunk during the Falklands War in 1982 by HMS Conqueror.
